Updated xymon packages fix security vulnerabilities: The incorrect handling of user-supplied input in the “config” command can trigger a stack-based buffer overflow, resulting in denial of service (via application crash) or remote code execution (CVE-2016-2054). The incorrect handling of user-supplied input in the “config” command can lead to an information leak by serving sensitive configuration files to a remote user (CVE-2016-2055). The commands handling password management do not properly validate user-supplied input, and are thus vulnerable to shell command injection by a remote user (CVE-2016-2056). Incorrect permissions on an internal queuing system allow a user with a local account on the xymon master server to bypass all network-based access control lists, and thus inject messages directly into xymon (CVE-2016-2057). Incorrect escaping of user-supplied input in status webpages can be used to trigger reflected cross-site scripting attacks (CVE-2016-2058). Note that to effectively fix CVE-2016-2055, the /etc/xymon/xymonpasswd configuration file should be owned by user and group apache with 640 permissions.
